MISA PRAIRIES 2013 - Flexibility in Delivering GIS Services
GEOALBERTA 2013 - I Spy With My Little Eye - St Albert
1. I Spy With My Little Eye
An Aerial Imaging Strategy for
St. Albert
Tammy Kobliuk – City of St. Albert
2. Pictometry and St. Albert
• A little about us
• How our imagery has evolved
• Where Pictometry fits into the picture
• Building the business case
• Our current status
• A window into how it is being used
3. A Little About St. Albert
• Capital Region – beside Edmonton
• Approximately 61,000 residents
• Approximately 50 sq.km. (small)
• Primarily urban residential (yuppies)
• High service delivery expectations (you have no idea)
• High taxes (so we’re told over and over again)
• God’s country (even the magazines say so!)
• The Botanical Arts City
4. Our Imagery Evolution
• Hardcopy 9x9’s
• Black and white scanned photos
• 25 cm black and white digital orthophotos
• 10 cm colour digital orthophotos
• LiDAR DEM and Surface Model
• Pictometry (partial coverage and level)
• Pictometry (completion and in-fill)
• Pictometry (complete coverage)

5. Where Pictometry Fits
• We see it as a vital part of our
imaging strategy
• In a very short time it has
become very important to a
lot of staff
• We automatically assess new
staff for their need of it
6. How It Looks Now
• Capital Region (ERJOI)
– Every two years
• Pictometry
– Every two years
– Offset from ERJOI
• LiDAR
– Every five years
7. Building the Business Case
• Provides a digital view unavailable from other
sources.
• Increases the ability to do work from the desktop.
• Decreases the need for field visits.
• Provides a detailed daytime view for night time
work (e.g. emergencies)
• Cost effective compared to regular photography.
• Cost effective to roll out to users.
• Access to other client image libraries.
8. Return on Investment
• No visible budget decrease
• Increases the efficiency of existing staff
• Provides a more complete information picture
to capture better data
• Provides a more complete information picture
to make better decisions
• Cloud software has minimal impact on
required IT resources
9. Pictometry and LiDAR
• Pictometry is 3D aware
• DEM used to embed Z information into each pixel
• Quality of source Z information affects:
– Quality of reference points
– Embedded pixel elevations
– Image registration
• Which in turn affects:
– All measurements
– Elevation contour generation
– GIS data overlay accuracy
10. Our Current Status
• 7.5 cm resolution
• We now have full coverage at all levels
• Urban area – 2012 coverage
• Rural area – 2013 coverage
• Active construction areas – 2012 and 2013
• 103 active POL users
• Users in almost every department
• OUR MOST POPULAR GIS APPLICATION
11. Deployment
• Currently Pictometry Online
• Only two ArcGIS extension users
• iPad mobile application
• Planned: Smartphone mobile application
• Planned: Geocortex Essentials integration
12. Pictometry Online
• Viva la cloud!
• 100 concurrent user level
– 500 named users
• A number of GIS layers loaded
– We take the lead from our users
• 95% of users are required to take training
• Little requirement for technical support
13. Pictometry Online
• Turn-key
• Easy to use
• Easy administration
• Can be a bit flakey
• Clunky as far as GIS goes
• Cool that we can see Edmonton
• Manual upload of shapefiles or KML
• Needs work on cartographic capabilities
• Needs work on reporting
• Future: SDE data connections
14. Our Biggest Users?
• Assessment
• Recreation
• Public Works
• Engineering
• Development
• Fire Services
• Municipal Enforcement
15. Use Case: Property Assessment
• Checking property conditions against real property
reports
• Checking for additions
• Checking measurements
• Pre-visit preparation
17. Use Case: Bus Stop Review
• Need to check every bus stop in the city
• What does the location look like?
• What infrastructure is there?
• Ground conditions?
• What infrastructure?
• Cost planning
• Making measurements
18. Use Case: Park Infrastructure
• Where is the
infrastructure?
• What type is it?
• How does this
match to our
non-spatial
information?
19. Use Case: Fire Pre-Planning
• General property layout
• Structure shape and size
• Structure materials
• Building/property entry points
• Access barriers
• Fire infrastructure locations
• Roof layout
– Vents
– Access points
